查询词典 Gesneriaceae

However, among zygomorphic Gesneriaceae species, some species have evolved from zygomorphy back to actinomorphy.

相较於辐射对称花，两侧对称花常具专一传粉者并有较高的授粉效率，故其种化速度亦常较前者来得快。

In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.

我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异，经由子叶面积大小的测量，欧洲苦苣苔成员两片子叶呈现相似的生长速率，因此维持两片子叶等大的特徵，然而堇兰的大小子叶的确具有不同的生长速率，使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。

Any of numerous,mostly tropical herbs or shrubs of the family Gesneriaceae,including African violet s,the Cape primrose,and gloxinia.

苦苣苔类一种大量的、主要长于热带的苦苣苔科草本植物和灌木，包括非洲紫罗兰、好望角樱草和大岩桐

Gesneriaceae, including African violets, the Cape primrose, and gloxinia.

科'。''草本植物和灌木，包括非洲紫罗兰、好望角樱草和大岩桐

Further examinations of cell size, trichome distribution and meristematic activity failed to find any differences between cotyledons of European species. All observations showed that both cotyledons of European Gesneriaceae species ceased to grow in early stages and thus no prolonged meristematic activity could be observed.

进一步检测子叶的细胞大小、毛状物的分布、及分生组织活性检测均显示欧洲苦苣苔科成员的两片子叶在发育早期已停止生长，两片子叶间也无形态上明显的差异，同时也无法观察到持续的分生组织活性刺激子叶持续生长。

These isocotylous species thus provide a great opportunity to investigate how anisocotyly develop, and loses during Gesneriaceae evolution.

这些丧失子叶不等大的种，对比於仍具备子叶不等大的近缘种，提供了我们得以比较研究苦苣苔科子叶不等大发育机制的转化及其演化上的影响。

Anisocotyly is common in Gesneriaceae, which refers to that both cotyledon are unequally developed. The macrocotyledon can continuously grow while microcotyledon ceases to grow after cotyledon expansion.

子叶不等大是苦苣苔科植物特有的现象，在种子发芽后，其中一片子叶会藉由分生组织持续生长而成为大子叶，另外一片子叶则无法持续性的生长而形成小子叶。

The utility and systematic significance of some pollen characters in Gesneriaceae were also discussed.

还讨论了一些花粉外壁纹饰特征在苦苣苔科的系统研究方面的潜在价值。

One new genus and one new recorded genus of Gesneriaceae from Yunnan.

云南苦苣苔科一个新属及一个新记录属。

Phylogenetic analysis demonstrates that the two CYC-like genes, ObCYC1 and ObCYC2, belong to GCYC1 and GCYC2 clades in Gesneriaceae, respectively.

CYC 类基因的分子系统学研究已经在苦苣苔科Gesneriaceae中展开，但是还缺乏对这些基因表达和功能的研究。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
